SPECIFICATION forming part of Letters Patent No. 350,626, dated October 12,1886.

Application tiled September 5, 188?. Serial No. 105.028. (Nu mode'.)

To (LZZ whom it may concern) 7 Be it known that we, ALBERT T. HESS, a citizen of the United States, and HANS A. S'roL'rENnERG,an alien subject of the Emperor of Germany. residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in a Hotel Oalland Automatic Fire'Alarm and Indicator, of which the following is a specification.

The object of our invention is to furnish a simple and complete system, by means of which the following results are obtained: A separate call or signal may be given from the office or any central point in the building to any room in the building; a call=or signal may be given from the office to an engine-house or other outside point; a call or signal may be given from any room in the building to the office or any central point in the building; a general or simultaneous call may be given from the office to all the rooms in the building and to the engine-house or any outside point; a general or simultaneous call may be given from any room or hall in the building to the office or any central point and to all other rooms and halls in the building and to the enginehouse, and when such call is given the number or location-of the room or hall from which the signal or call is given is indicated in the otlice or other central point, and the number of the box indicating the building and'the particular room or ball in the building from which the call or signal is given is indicated by suitable signals in the engine-house. In addition to these many results, we obtain an automatic general alarm or simultaneous call, from eachor any room or hall in the building to the office and to the engine-house, said last-named general alarm also giving in the office or at any central point in the building the number of the room or hall, or thelocation of the same, from which the general alarm arises, and giving in the engine-house or any desired point or place outside of the building the number ofthe box designating said building and the number of the room or hall, or the location of the same in the building, from which such antomatic general alarm is given. This automatic general alarm is caused by the increased temperature of the room through or by the means of thermostats, in the ordinary manner, so far as initiating the series of alarms herein described is concerned.

\Ve have illustrated our invention by the drawings accompanying this specification and forming a part hereof, in which Figure 1 is a general view illustrating the system of laying the wires and making connections thereof in the building. plan illustrating one way in which the general circuit closer required to complete the circuit between the series of batteries and all the difl'erent rooms and halls in the building may be constructed. Fig. 3 is an elevation of the same with the circuit-closer in the position shown in Fig. 1. Fig. 4 is an elevation illustrating the same turned to give a general alarm, and also illustrating in a general way the manner in which the alarm is signaled at the engine- Fig. 2 is a house. Fig. 5 is a front view ofthe circuit-closer and generalalarm circuit-closer in the different rooms and halls of the building. Fig. 6 is a front view of the office circuit-closer and generalalarm circuit closer, detached the one from the other. Fig. 7 is a cross-section of a circuit-closer made in the form of a push-button. Fig. 8 is a general view illustrating one way in which the number of the box indicating the building and the location'of the room or hall in the same may be given at the engine-house or other outside point. Fig. 9 isa cross-section of the annunciator on line 9 9 of Fig. 8. Fig. 10 illustrates a second of the many ways that may be adopted of constructing the general circuit-closer.

Like letters refer to like parts throughout the several views.

I II III IV are batteries. r

A is one of the poles of the battery or batteries. X is the other pole of the battery or batteries.

Any suitable number of batteries are employed.

a a a are wires running from one pole of the battery to a point in close proximity to, either over, under, or to one side of, a general. circuitcloser, O.

B B B are electric bells placed in the rooms and halls of the building, and electrically connected with wires 0/ a. a.

b I) b are wires electrically connected with signals B B B, and extending from said sig nals to the opposite poles of the battery. A complete metallic circuit, which we will term circuit No. 1, is thus ibrmed,when circuitcloser C is closed: from batteries I II III through wires (6 a a, general circuiteloser 0, wires a a a, bells B B B, and wires b b b, back again to the batteries.

(6- is a wire electrically connected with one pole of battery III or with wire a, as preferred, and running to the electro-magnet 1), through the coils of said electro-magnet, to and through general circuit-closer (l, and to the circuit-closers E, placed in the various rooms and halls of the building. Vire a is electrically continuous through general circuitcloser 0 when the same is in the position shown in Figs. 1, 2, and 3,and is disconnected or broken when general circuit-closer G is in the position shown in Fig. 4.

e is a catch, notch, or step operated by armature d. v

F is an arm or lever secured at one end to cireuit'closer C, and resting at or near the other end upon catch 6.

f is a weight secured to the free end of lever F.

When circuit N o. 2 is closed, armature (Z is brought forward by electro magnet D, and lever F is released from catch 6. General. circuit closer G will be closed by lever F and weightf, or an equivalent spring, and circuit No. 1 will be closed.

The form of switch shown in Fig. 10, or any suitable key-switch or circuit-closer, may be adopted in place of the form shown in Fig. 1, as the particular mechanism employed in no way ail'ects the manner of operation of circuits Nos. land 2.

The construction illustrated in Fig. 10 is as follows: (3 is the dial. cl is the armature of magnet D. 1 is a piece of metal or other conductor inserted or inlaid upon the face of dial G. Dial 0 having arm or hook in, actuated by spring N, is used as a circuit-closer. Dial C is held in the position here shown by catch e on armature d. a a a are wires running from one pole of a battery to a point in close proximity to and over dial 0, and to one side of pieces of metal g, inlaid orinserted, as above described, in the face of dial 0 a a a, (inclusive) are wires placed in the same relative position to dial G and conductors g as wires a a a, and run to the various rooms and halls in the buildin \Vires a a a are electrically connectedwith wires (1 u a by conductor 9 on dial 0 when the dial revolves or is rotated (by spring N) sufficiently to bring conductors g underneath said wires. X'Vircs a a a are connected with bells in the various rooms and halls of the buildin All the wires in Fig. 10 perform like service and are identical with wires having like letters in Fig. 1. Vires c, c, (1-, a, h, and 74- are all placed in the same relative position with dial 0 and conductors g g g, excepting that wire (1-, by means of the conductor g,is electrically continuous through dial 0 when the dial is in the position shown in Fig. 10, and is broken when dial 0 is in the position it assumes when catch c is released. It will be seen by inspection ol' Fig. 10 that when catch a is in any way released dial C will partially rotate, actuated by springN.

The seve 'al circuits shown or illustrated in Fig. 10 are as follows: circuit No. 1, from one pole of the batteries (not shown in Fig. 10, but seeFig. 1) on wires (1 u a, conductor 9, g, &c., (when dial C is partially r0tated,) wires (1" u a. to the bells in the difierent .rooms, and by return-wires back to the batteries; circuit No. 2, (closed by circuitcloser E, Fig. 1,)

place between the wires (0- and b, as shown in Fig. 1; or thermostat H maybe placed in circuit-closer E, as also shown in Fig. 1. Thermostat H automatically closes circuit No. 2 when the temperature of the room, hall, or building is raised to the proper degree, and

the same result is produced as if circuit No. 2

were closed at will.

c. a a are wires running from one pole of the batteries or from wires a a a through sigbis a wire running from circuit-closer G t0 wire Z).

b is a wire from circuit-closers E and G to an annunciator, I. Annunciator I has bell K placed thereon, when desired.

a is a wire from annunciator I to one of the poles of battery III.

A circuit, which we will term circuit N o. 4, is thus formed when circuit-closer G is closed: from the battery through wire a, annunciator I, wire I), circuit-closer G, wire 12-, and wire I) to the battery.

1/ is a wire from eireuit-closer E to wire Z).

A circuit, which we will term circuit No. 5, is formed, when circuit-closer E is closed, from the battery through wire a, annunciator I, wire I), circuit closer E, wire 12, and wire I) to the battery. As the closing of circuit-closer E closes circuit N o. 2 and circuit No. 5, they are at all times opened or closed simultane ously.

and electrically connected with wire aat any point between circuit-closer O and circuitclosers E.

desired, and also automatically actuated by lever F.

p p are catches, placed, respectively, on dial M and lever P. I

N is a spring, turning the dial M by lever on when catches p p are released.

tion of the dial.

The actuating of any one ofthe shields 1 2 3, &c., in the annunciator I, makes a continuous wire from dial M on wire 71/71", 850., metal i,and wire 11- to the ground. The actuating of dial M will then alternately close and break what we term circuit No. 9.

The movementor actuating of any one of the shields is caused by the closing of circuit N0. 5, (or by the closing of circuit No. 4; but if done by closing of circuit N0. 4, circuit No. 9 is not affected.) Circuit No. 5 is closed by circuit-closer E, which at the same time closes circuit No. 2; hence, when circuit No. 5 is closed the room or hall or other place in the building in which circuit-closer E is actuated or closed is shown on the annunciator, and at the same time, by the closing of circuit N0. 2, circuit-closer G is actuated and circuit No. 1 is closed. As circuit No. 9 is closed as far as dial M, on dial M being actuated as arms 1:1 12, &c., pass by wires h If, &e., circuit No. 9 is alternately broken and closed, and the de sired signal given at the engine-house. The electric current over circuit No. 9is generated by a battery placed either in the building or in the engine-house.

A suitable register is placed in the engine. house'toreccive thesignalssentoverorthrough dial M.

The pins or protubcrauces l 2' 3, &c., on dial M are each connected at the center of the dial by the cross wires 1' r r with the wireleading to the engine house, as shown in Fig. 8.

In Fig. 8 is shown circuit No. 1, from batteries I II III through wires a a a, circuitcloser 0, wires a a a, bells B B B, and wires 1) b-b, back to the batteries; circuit No. 2, from battery III at A, through wires a-, electro magnet D, wire a-, circuit closer 0, wire a,

In Fig. 8, batteries 1 II. I II, cireuit-closer G, circuit-closer 0, rooms 1 and, 2, annunciator I, electro-magnet l), and the various wires, circuit-closers, and switches connecting them, are identical with the same things shown on Fig. 1, and are lettered the same, Fig. 8 being 1 intended chiefly to illustrate dial M, with the connections more particularly pertaining thereto.

W'i re a may be constructed as a branch ofreturn-wire Z). ires (1 a. u" may he considered and are branches from wires (1 (1 a, and connect wires (ru (l and u" u a, through ci reuit elosers 1 2 3,&c,on board, 0 as the desired circuit-closer is actuated precisely as wires 0' a (I and a a a s are connected, simultaneously, by general circuit-closer 0. \Vi res 1) maybe considered and are continuation of wire n' after passing through the annunciator I. 1t will thus be seen that by short aiuliuexpensive branches suitably constructed on circuits formed by the outgoing wires (1, u-, and u and the single returnwire I) we are able to sccurewhat may be termed nine several and distinct electrical circuits, and by the system of working these circuits singly and doubly (here set forth) we are enabled to secure the many results shown and described in this specification, the great value and utility oi which are so evident as to require no explanation or illustration.

The manner of operation of our invention is as follows: \Vhen it is desired to ring the sig nail in the oi'lice or any central point in the building from any room and announce the room t'rom which the ring is given -to said office or eentralpoiut by means of the annunciator, circuit-closer G is closed. Circuit No. 4 is thus closed, and a current of electricity passes over wire a from battery III through aniumciator, over wires I)", through circuitcloscr G, over wires Z1- and wire [1, back to the battery III. \Vhen it is desired to ring the bell in any room from the office or central point, circuit closer O is closed. A. current ot' electricity then passes from one of the series of batteries 1 11' 111' over wires a, through circuit-closer C, over wires u, through signal B, and over return-wire I), back to the battery. If it be desired to send an alarm from the office or central point to the engine-house, catches 1) 1) are released by lever P, when spring N moves dial M, alternately breaking and closing circuit N0. 9, and a current of electricity flows through wires 71,-, dial Mi, (over 7%,) and over wire h to the engine'house and returl'l, either by wire 7! or by the ground. It" a gen eral alarm is desired to be given from. the o'l'lice or central point, armature d is pressed forward by the operator, or circuit-closer L is closed. Vhen circuitcloscr Lis closed, armature d is brought forward by the current of electricity on circuit No. 6, over wires a, cirm1it-closer L, wires to a, through electro-magnet 1'), and then over wire c'to the battery, releasing the lever F from catch 0,- or, as stated before, armature (Z may be brought forward by the op erator directly, and lever F released from catch a. General circuit-closer G is then closed by weightf and lever F, thus closing circuit No. 1. A current of electricity then flows over wires a, general CllOllllrUlUSCl. 3, wires a, signals B, and wires 1), back to the battery. At;-

means of piece of metalg, closes wires '11 and h-,'(in the form of construction shown in Fig. 1,) and a signal is sent to the engine-house or other outside point, and in the form of construction adopted and shown in Fig. 8, dial M alternately makes and breaks said circuits Nos. 8 and 9, and the signal is sent to the engine-house, giving in both cases the number of the box indicating the house or building. in the latter'casc, to send the signal the catchlever P is retracted, whereupon the dial M, is

rotated by the spring N through the intermediancy ot'thc arm m. It it be desired from any room in the building to send a general alarm, to the oifice, to all the roomsin the house, and to the engine-house, it is merely necessary to close circuit-closer E, closing circuits Nos. 3 and 5. A current of electricity will then flow from battery I It Over wires 0/, annunciator I, wire I), through circuit-closer 1*], over wire I), and over wire I) to the battery, connecting armature-controlling shields 123, &c., on annuir ciator I, and exposing them to view, and at the same time the current of electricity will flow from battery Ill over wire u through electro-magnet D, over wire uthrough circuitcloser E, over wire I), and over wire Z) to the battery. By the movement of the armature (Z (caused by the current through the electromagnet D) weight f on lever F closes general circuit-closer O. closer O breaks circuitNo. 2 before circuit No. l is closed. by said circuit-closer O. 'lheelectrical current generated by battery Ill. will therefore, together wit-h the electrical current generated by batteries I and It, pass over clec trieal circuit No. 1-that is, from batteries I II III, respectively, over wires a, through. general circuiteloser I, over wires a, through. signals B, and over wire I) to the batteries. The falling of lever F automatically releases lever P and catches 1) p, and dial M partially rotates, and a current of electricity passes through. circuit No. 8 over wires h, through dial M, (7'03) and through wire 7z., giving the number of the box indicating the building at The closing of circuit-' the same time general circuit-closer (l, by I TIO the engine-house, and after the number indicating the building has been given by circuit No. 8 the dial continuing to turn, circuit No. 9 is alternately broken and closed over Wire h, through dial M, over any one of the wires 11' 2'1, 850., over the corresponding wire, h if, &c., and piece of metal a on the shield, and then over Wire hto the enginc-house, thus giving also the number of the room from which the signal is given. In case of fire in any room, hall, or other portion of the building, and the failure to promptly give an alarm, as herelast described, upon the temperature in the portion of the house Where the fire is arriving at a certain point the thermostat Hwill close circuits No. 2 and No. 5, as just described, and thus an automatic alarm will be given similar in every respect to the alarm last described.
